Job description

An active Top Secret/SCI Clearance with a Full Scope Polygraph is required.

This is a hybrid schedule with up to 3 days/week remote and 2 days/week onsite in Annapolis Junction, MD.

We have an immediate need for a Front-End Developer with a strong concentration in Section 508 accessibility compliance to ensure the RAD system's interfaces are fully usable by individuals with disabilities. The ideal candidate combines solid front-end engineering skills with deep, hands‑on expertise in accessibility testing and remediation, including proficiency with screen‑reader technology. This role involves close collaboration with a cross‑functional Agile team of software developers, system engineers, and product owners to build and validate accessible, compliant, and high‑quality user interfaces.

Responsibilities

• Accessible Front-End Development: Design, develop, and maintain front‑end components and user interfaces that conform to Section 508 and WCAG 2.1/2.2 AA standards.
• 508 Testing & Remediation: Perform comprehensive accessibility testing using JAWS and other screen readers, identifying and remediating issues related to keyboard navigation, focus management, ARIA implementation, color contrast, and semantic HTML structure.
• Audit & Documentation: Conduct manual and automated accessibility audits, document findings, and produce test reports as needed to support agency compliance requirements.
• Collaboration: Partner with UX/UI designers, developers, and product owners early in the design process to bake accessibility in by design rather than retrofit it, and provide guidance on accessible design patterns.
• Integration & Delivery: Work with QA and DevOps to integrate automated accessibility testing tools (e.g., axe-core, Pa11y, Lighthouse) into the CI/CD pipeline for continuous compliance monitoring.
• Collaboration & Ceremonies: Participate actively in Agile ceremonies (sprint planning, demos) and communicate accessibility requirements and tradeoffs to both technical and non-technical stakeholders.

Required Technical Skills

• Proven experience developing front‑end applications using modern JavaScript frameworks (Vue preferred).
• Hands‑on expertise testing with JAWS screen reader, with working familiarity of other assistive technologies.
• Strong knowledge of Section 508 standards, WCAG 2.1/2.2 (Levels A/AA), and ARIA authoring practices.
• Experience with semantic HTML, accessible form design, keyboard navigation patterns, and focus management.
• Proficiency with accessibility testing/auditing tools (e.g., axe DevTools, WAVE, Pa11y, Lighthouse).
• Experience with version control systems (Git) and Agile collaboration tools such as Jira and Confluence.

Desired Technical Skills

• Experience producing VPATs/Accessibility Conformance Reports for federal agency review.
• Familiarity with integrating automated accessibility checks into CI/CD pipelines (e.g., GitLab CI/CD).
• Experience with Cypress or similar tools for automated UI/accessibility test scripting.
• Familiarity with Cloud-based architecture and deployment (Amazon Web Services).
• Familiarity with domain knowledge surrounding government agency reporting and dissemination policies.
